TOTAL-ADDING WEIGHING-SCALE.

Be it known that I,- WILLIAM Moon, a citizen of the United States,residing in Dayton, 'in the county 'of Montgomery and ;State of Ohio,have invented certain new and useful Improvements in Total-AddingWeighing-Scales, of which the following is a full, clear, and'exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

" My invention relates to weighing scales, inwhich the weights areindicated by the movement of a pointer overagraduated dial,

' and the-object of the invention is to provide weighin scales,

suitable counti an. attachment to be applied to such dial whereby thevarious separate-loa s of such particular commodities as desired, orallthe various loads,weighed on. the machine may be severally registeredon g wheels, and the totals, of

these amounts added up .so that it may be at once determined the totalamount of the particular commodities that have been weighed .in anyde'sired interval of time.

My invention consists of that novel construction and arrangement ofparts, to be hereinafter particularly pointed out and claimed. i

In the drawings Figure 1 is a side elevation illustrating myimprovements. Fig 2 is a rear elevation of same. Fig. 3 is a de-.

tail longitudinal section vof the frictionclutch for connecting theauxiliary shaft for actuating the total adding'devices with the .thewell known constructions of main shaft of the dial indicator. Fig. 4 isa detail cross section of the auxiliary shaft showing the connectiontherewith of the counter engaging pitman. Fig. 5 is a detail view of theratche and pawl which prevents any back movement of the auxiliary shaft.

1 ist'he pointer and 2 the dial plate of the weighing machine, the dialbeing aduated for any weights within the capacity qf the machine, andthe pointer is mounted on the main shaft 3, having suitable bearlngs 1nthe frame 4 and easing 5.

I have not illustrated the mechanism of the weighing scales either inthe platform construction or the pointer actuating construction, asthese features of the scale form no part of my present invention, andany of weighing scales may be em loyed. I I '6 is. the rod Whlchconnects the indicatin and other mechanism within the case 5- wit% theplatform mechanism,

total adding specification ofLetterslatentJ P t nt t, 11, 1910, v a.Application and October 21,1909. Serial in.

In applying my invention to the weighing scales, I extend'the mainshaft. 3 which rotates the pointer out through a suitable bearmg in therear of the case, and on this shaft.

is securely mounted to rotate therewith the gear 7 proper number ofteeth so'that the movement of the gear will correspond with the movementof the pointer 1 over the dial, and when it is desired to register themovements of the gear for adding up the amounts weighed as indicated bythe pointer, the pinion 8 of the counting mechanism-is brought into enagement with this gear, as will be hereina ter described, Any of thewell known constructions of v counting wheels may be provided, and haveillustrated a series of five of ,such counting wheels 9, mounted on theshaft 10 suitably journa-led in a casing 11,

This gear 7 is provided with the i the shaft 10 carrying the pinion 8,so that suspended by its frame 11, pivotally mounted on the pin or stud12, secured to the casin 5, above the gear wheel 7, 13 is a coiled sring mounted on the stud 12 between the fiame and the casing, one end ofthe spring being secured to the casing, and the other end bearing ontheframe and tending to hold the pinion will actuate'the the-frame andcounter mechanism, with the lpinion 8 disconnected from the gear 7. I

ave not shown the particular construction of counting mechanism, becauseany of the well known devices forthis purpose may be employed, but itwill be understood that the proper number of counting wheels, gears,pawls'and shafts are employed to register any desired number of turns-ofthe pinion 8,

and also with suitable re-setting devices to re-set the counters to zerowhen desired.

Mounted in suitablebearings in the standard 14 attached to the mam frameof themachine, is anauxiliary shaft 15 in alinement with the main shaft3 of the dial mechanism. The outer rear endof the shaft 3 has securelyinned thereto the male clutch member 16 and has securely pinned theretothe female clutch member 17. These clutch members are normally out ofcontact, the shaft 15 having an endwise movement in its bearings 1n thestandard 14, and a coiled spring 16 mounted on the. shaft 15 and bearingbetween the the inner end of the shaft 15 standard and the disk 18,pinned to the shaft 15, holding the clutch members apart. The disk 18carries a cam lug 19 which, when the parts are atrest, engages a recessin the retaining disk 35 which is loosely mounted on the auxiliaryshaft, and securely pinned to the standard. 21 is the operating handlefor the auxiliary shaft 15, and as soon as this shaft is rotated by thehandle 21 the cam lug 19 rides out of the recess in the retaining disk,and overthe face of the disk, and inasmuch as the clutch engaging disk18 is keyed to the shaft 15, as soon as the operating handle is turnedthe shaft will be shifted inwardly to cause the friction clutch members16 and 17 to en age and thereupon the auxiliary shaft 15 vill be coupledto the dial shaft 3.

Mounted on the shaft 15 and pinned thereto, is the cam disk 20 formedwith a cam groove 22 which engages the lug 23 on the lower end of thecounter connecting pitman 24. The upper end of this pitman is pivotally'connected to a depending lug 25 on the counter casing, and the lower endof the pitman is provided with an oblong slot 26 through which theauxiliary shaft 15 passes. It will be evident from this that as theshaft 15 is rotated the lug 23 will ride out of the recess 22, in thecam disk 20, drawing downwardly the pitman 24, and with it the countingmechanism, so that the pinion 8 will be brought into engagement with thegear 7. I

27 is a ratchet wheel pinned to the shaft 15, and engaged by the springpressed pawl 28 pivoted on the standard by means of which any backmovement of the shaft 15 is prevented. i

Normally the operating handle 21 is. held against a stop latch 29 which-is carried by the arm 30, pivoted in the lugs 31 on the standards. Thelatch 29 is normally held in the pathway of the operating handle by thecoiled spring 32 seated in a recess in the standard, and bearing uponthe under surface of the latch, and 33 .is a disk carried by the latch29 in a convenient position to be depressed by the hand of the operatorwhen grasping the handle to release the latch. The operation of thedevice will be sufliciently evident-from the foregoing description.

As I have heretofore stated, the ordinary mechanism for indicating theamount of the load on the scales is contained in the case 5, and by thismechanism the pointer will be moved to the proper position on the dial,and as soon as the load is removed from the platform, the pointer willbe automatically returned to zero, and stopped at the zero point in theusual way for such indicating scales. Inasmuch, however, as the gear 7is secured on the pointer shaft, this gear will also be rotated witheach movement of the pointer.

the operator,

Should the user, however, desire to know how many pounds may have beenweighed on this scales during any given interval, or should he desire tokeep a record of the amount .of any particular commodity that may beweighed, he then makes use of the total adding attachment. The scaleswill then be used for all other commodities in the usual way, thepointer being automatically returned to zero, and no registration beingmade except for the particular article desired. For example, a grocermay desire to keep a statement of the amount of sugar sold, and in thatevent he would operate the total adding mechanism only when sugar wasweighed on the scales, and the scales could be used for other articleswithout any list being kept. In order to keep this list of allcommodities, or any particular commodity that may be weighed, before theload is removed from the scales, the operator grasps the handle 21,releases the latch 29 by depressing same, and rotates the shaft 15. Thismovement rotates the disk 18, brings the lug 19 out of the recess andagainst the face of the disk 35. The friction clutch 16, 17 is actuatedand the pointer. returned to zero, Where it is stopped by the usualstop. The friction clutch is not sufficiently powerful to prevent thefurther rotation of the shaft 15 by the handle 21, after the pointer andthe main shaft 3 have been stopped, and

therefore, completes the revolution of the operating handle, the handlebeing stopped at its normal position by the latch 29.

In addition to coupling up the main shaft 3, the rotation of theauxiliary shaft 15 rotates the cam disk 20 which, in turn, draws uponthe pitman 2 1,'bringing the pinion 8 into mesh with the gear 7 so thatthe movement of the gear is recorded on the counting wheels. The moment,hewever, the shaft 3 and the pointer 1 are stopped, upon the pointerbeing returned to zero, is also stopped so that only the amount weighedis recorded on the counting wheels. As the operating handle 21 isreturned to its normal position, the lug 23 on the pitman enters therecess 22, in the disk 20, and the coiled sprin 13 draws the itman tothe lower end 0 the slot 26 and isconnects the pinion 8 of the countingmechanism from the gear 7. In this way the total amount weighed by thescales of any desired loads 3 is accuratel indicated.

Having t us described my invention what I claim as-new' and desire tosecure by Letters Patent, is:

1. In a device of the character specified,
